used for metallizing act as current conductors, and the polypropylene as a dielectric.
After the manufacturing process and a quality control,the capacitive elements (coils)
in aluminium or plastic cans, and then encapsulated with polyurethane resin,
which is ecological and non-toxic. This resin is specially designed by
the RTR Energía S.L.’s Chemistry Department and can be used with different capacitors and electric equipments which need encapsulation
